The Universe Revealed

💡Universe became transparent for the first time as electrons bound with protons to form atoms.

🌈Light emitted when universe was 3,000 Kelvin and 380,000 years old, observable in all directions.

Mysterious Alignments

🌀Microwave background split into different poles revealing temperature variations

🌠Cosmic microwave background slightly hotter in direction of Milky Way's motion

The Lensing Effect

🔭Simulation recreated patterns in cosmic background with super cluster of galaxies

❓Idea of lensing by large structures raises multiple unresolved problems

FAQ

What is the cosmic microwave background?

The cosmic microwave background is the residual radiation from the Big Bang.

Why is the 'Axis of Evil' considered mysterious?

The unexplained alignment challenges our current understanding of the universe.

How do massive objects affect light paths?

Massive objects curve space, causing light to bend as it passes by.

What causes the slight temperature differences in the cosmic microwave background?

The motion of Earth, Sun, and Milky Way through the universe leads to temperature variations.

Can the lensing effect be observed in everyday life?

The lensing effect by large structures is not directly observable but can be inferred through simulations and observations.

Is the alignment of the cosmic microwave background axis significant?

The alignment perpendicular to the dipole axis and parallel to the solar system axis raises intriguing questions about cosmic structures.

How old is the light emitted by the universe?

The light was emitted when the universe was 380,000 years old and had a temperature of 3,000 Kelvin.

What is the dominant dipole feature in the cosmic microwave background?

The dominant dipole feature is attributed to the motion of Earth, Sun, and Milky Way through the universe.

Why do questions arise about the accuracy of our universe models?

The discovery of anomalies like the 'Axis of Evil' challenges the completeness of our current models.

How does the lensing by large structures impact our understanding of the universe?

The lensing effect introduces complexities in interpreting cosmic microwave background data and the distribution of matter in the universe.
